> The average user appears to care enough to go out of their way to use browsers and extensions and such that block ads
The average user isn't going out of their way to use ad block, at least globally. Last estimates I remember are still around only 30% of internet users using an ad blocker unfortunately. Ad blocker adoption is heavily skewed toward techies.
It's an even lower amount of people on mobile, where the 'average user' spends the majority of their time.
